Just wanna ask if anyone could help me find a service manual for astrophysics 100XD x-ray machine.
Basically I have been given a task by my boss to test a mobile x-ray machine which i did it for a very first time. When I power up the system, everything works fine as I've seen it rollers moving back & forth when I press the forward and reverse button. But when I put an object inside the x-ray machine, there is no image came out on the screen monitor. It shows only vertical lines just like a bar coded lines instead of the usual image of the thing that i put inside.

Is there any lens on the x-ray machine that needs to be clean? What other possible causes of this problem?

I have found the problem by removing the x-ray generator then trace the v.24 interface cable connected to the PC leading to the series of cards that provides the gamma rays. some of the connectors were detached which causes image not clearly displayed on the system monitor.
